Polo went in to limp mode/loss of power.

Engine management light and EPC light came up on the dash, plugged it into vcds and got these errors

I think my throttle body may just need cleaning.

Is there a guide on how to do this?

I'd expect a legal full version of VCDS to be a bit more specific, and decode any of these codes as being due to a throttle body problem - if that was the case. Or have you done some research into what these codes normally or caused by.

Generally speaking, remove throttle body, spray it with carb cleaner, if fitted, remove the interface plate and clean it fully especially around the EGR pipe port, use legal version of VCDS to perform basic functions - ie re-learn end stop voltages.

I'm guessing that the OP has a petrol engine car - ie it has a throttle body assembly!
